Im not in california, so I dont know anything about it.  Ortho is not one of my specialties

This is what I found with CA WC

http://www.dir.ca.gov/dwc/

here you have access to laws, regulations & tons of other info.

I am not a lawyer.  My post is not legal advice. You are free to seek a lawyer at your own expense for legal answers. Your asking for my layperson guidance holds me harmless and indemnifies me and the MAB against any and all lawsuits. We are not an approving agency. My name is, and I approve this message!  Im sorry, Im not in at the moment, at the tone, please leave a message.... BEEP!
